Situated west of Los Angeles, the Channel Islands Biosphere Reserve represents one of the last examples of natural Mediterranean ecosystems in North America and some of the few remaining natural southern California coastal ecosystems. Characteristic features are coastal sage scrub communities on the islands and exceptionally pristine tidepools on the marine terraces surrounding them. All of the islands have been altered to a greater or lesser extent by human activities, including fires, farming and livestock grazing, fishing and numerous house and road constructions. Many dominant plant species have been introduced as well as animals such as black rat (Rattus rattus) and European rabbit (Oryctolagus cuniculus). Manipulative research on exotic plants and animals is underway to determine their impacts and to develop effective management actions to eliminate their impacts. Unregulated tourism on the islands is another management problem. The Channel Islands National Park, which is situated within the biosphere reserve, maintains a visitor center and there are numerous educational programmes available. The local communities participate in management decisions through public workshops and hearings and a local Fish and Game Commission.
